General Chapter Information: Boston is a hub of innovation in energy sciences and petrophysics, home to research labs in universities, service companies and operators. A primary goal of this chapter is to connect the researchers in the Boston area with the diverse needs of practicing petrophysicists around the world.

For those who are SPWLA members, please confirm that your chapter affiliation is Boston (you can check that here:  For those who are not SPWLA members, please join the SPWLA (you can do so here:!  Beyond our local meetings, there any many other benefits to membership as described here:

Next Event:  The Boston Chapter of the SPWLA is pleased to sponsor a guided visit to Harvard’s Mineralogical & Geological Museum (link) for our next event on Friday, March 31st.  Our host will be Dr. Alonso-Perez, the museum curator, who has kindly agreed to show us the museum history, its spectacular minerals collection, and their ongoing research activities. Chapter members will have free entrance to the museum, sponsored by the chapter.  Significant others and children are also welcome to join the tour after paying museum admission ($12/adult, with discounts for children and seniors). We will meet directly in front of museum at 26 Oxford St, Cambridge, at 2:45 pm. After the tour, we will meet at John Harvard’s Brewery & Ale House in Harvard Square for a social gathering. Please RSVP for the meeting by sending a message, including your SPWLA member number, to by March 24th.

Future Events:

April 14, 2017: Romain Prioul, Program Manager Geomechanics at Schlumberger-Doll Research Center, will present a talk titled, Using cuttings to extract geomechanical properties along lateral wells in unconventional reservoirs. The lecture will take place at Schlumberger-Doll Research Center.

May 8, 2017: the Boston Chapter will partner with the SPE New York & New England Petroleum Section and MIT to jointly host Timothy Collett, Geologist at the USGS, as part of the AAPG Distinguished Lecture Tour. The lecture will take place at MIT.

 Officer Biographies

President: Andrew E. Pomerantz is the Geochemistry Program Manager at Schlumberger-Doll Research.  His research focuses on the development of novel techniques to characterize the chemical composition of kerogen and asphaltenes, including methods in mass spectrometry, X-ray spectroscopy, and infrared spectroscopy.  That molecular information is used to understand fundamental physical and chemical processes in petroleum such as asphaltene compositional grading and storage and transport in shales.   He graduated from Stanford University with a PhD in chemistry in 2005 and has co-authored 50 peer-reviewed publications.

Vice President: Ravinath Kausik K.V. is a Senior Research scientist at Schlumberger-Doll Research. At Schlumberger he has focused on the development of novel NMR and petrophysical techniques for porous media, especially unconventional gas and tight oil organic shale plays. He has developed new NMR pulse sequences and petrophysical workflows for better understanding various fractions of unconventional plays such as the stored gas, bitumen, producible oil, kerogen and bound water. He is also involved in the development of the next generation NMR relaxometry and diffusometry measurements for both laboratory and logging applications. He obtained a M.Sc. from IIT Madras, India and Ph.D. degree in physics from the University of Ulm, Germany.  He worked as a postdoctoral fellow at the University of California, Santa Barbara before joining Schlumberger-Doll Research in 2009.

Secretary: Julie E. Kowan is a Geomechanics Consultant with over 12 years’ experience helping operators drill safer, more cost-effective wells and plan field development by reducing non-productive Time (NPT) due to wellbore instability and improving production. Julie has expertise in unconventional reservoirs, pore pressure prediction, stress constraint, wellbore stability, fracture permeability and compaction and is also skilled at summarizing complex scientific models into digestible reports. Prior to launching J. Kowan Consulting, LLC and joining HXR Drilling Services in June 2016, Julie was a Geomechanics Advisor at Baker Hughes from 2009 to April 2016. Before being promoted to Advisor, Julie held several other technical geomechanics positions at Baker Hughes and GeoMechanics International from 2005 to 2009. Julie earned a Master of Science in Geology from Brown University and a Bachelor of Science in Geology from Rutgers University. 

Treasurer: Tancredi Botto
is a Principal Research scientist at Schlumberger-Doll Research, where he has contributed to and initiated a number of research projects based on nuclear technologies. Among those, he has developed and field tested a novel deep-reading density imager based on naturally occurring cosmic rays. He is also involved in nuclear modeling and microwave sensor research. Tancredi holds a PhD from the Vrije Universiteit, Amsterdam (1999) and a M.Sc. from the University of Genoa, Italy. Prior to joining Schlumberger in 2005 he worked on experimental nuclear physics as a Research Scientist at the MIT Laboratory for Nuclear Science.
